The main considerations of safe working procedures on electrical equipment are to ensure safety of workers and safety of the general public. In addition to this, the continuity of supply, and the welfare of plant is important.
To be able to work safely in general and on electrical apparatus in particular it is necessary to:
- be aware of the hazards;
- be trained in safe working practices;
- apply adequate control and supervision;
- communicate effectively; and
- think safety.
Effective communication is critical to reduce the risk of misunderstandings or miscommunication. When passing on instructions or information (in writing or verbally), ensure expectations are clearly understood, and any hazards or constraints are conveyed.
It is also important to have an understanding of electrical testing equipment and the personal protective equipment required when working on or within the vicinity of electrical apparatus. When conducting any type of switching operation, sufficient time must be allocated for:
- explaining instructions to workers;
- fitting earths properly;
- fitting locks;
- applying danger tags; and
- placing safety barriers.
